Problems solved by technology

[0008] If the configuration of the user equipment receiving data is inconsistent with the HS-SCCH channel type on the network side, the data transmission between the two parties cannot be carried out normally. In actual work, the time for adopting the new configuration between Node B and UE is likely to be inconsistent. In general, there will be a delay between the two, ranging from tens of milliseconds to hundreds of milliseconds
During this delay period, communication interruption and data loss may occur between Node B and UE due to configuration incompatibility

Embodiment Construction

[0061] Please refer to figure 1 , is a flowchart of a data transmission method provided by an embodiment of the present invention.

[0062] include:

[0063] Step S101, receiving a wireless link establishment message.

[0064] When the user equipment performs state transition, it may receive a radio link establishment message sent by the radio network controller RNC.

[0065] Step S102, sending a message including the activation time to the user equipment.

[0066] Assume that the activation time is T1, and the information including the activation time T1 may be HS-SCCH Order information, and the activation time T1 may be set as a parameter in the HS-SCCH order information. In addition, the information including the activation time T1 may also be other types of information, as long as the activation time information can be issued.

[0067] Step S103, when the activation time comes, send data according to the format of the HS-SCCH in the transitioned state.

Abstract

A method for transmitting data when state is transferring is provided. The method includes steps as following: a wireless link establishment message is received (S101); the message including an activation time is transmitted to a user equipment (S102); data is transmitted in HS-SCCH format in the transferred state at the activation time (S103). A device and a communication system for implementing the method are provided. Both a base station and the user equipment update configuration at the promissory activation time, while receive and transmit information adopting primary configuration before the activation time. Therefore, it is ensured that the configuration of both are accordant at any time, and it is avoided that the configuration of the base station and the user equipment are not accordant before completing down-link synchronization, thereby the failure of communication is avoided.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a data transmission method, device and communication system. Background technique [0002] The CELL_FACH enhancement technology is newly added to HSPA+ in the 3GPP (3rd Generation partnership project) R7 version. HSPA+ is the further evolution and enhancement of HSPA (High-speed Packet Access, high-speed packet access), mainly involving in CELL_FACH , CELL_PCH and URA_PCH states support HSDPA (High Speed ​​Downlink Package Access, High Speed ​​Downlink Packet Access) channel reception. [0003] When the cell is established, if the system supports CELL_FACH enhancement, the CELL_FACH state and CELL_PCH state need to be configured in the system message 5 / 5bit to receive the relevant information of the HS-DSCH (High Speed ​​Downlink Shared Channel), the relevant information includes Priority queue, channel code, HARQ (Hybrid Automatic Repeat Request, hybrid a...
